Distribution. In addition to the geographical data from the type series, three new recent findings of the species are from the northwestern extremity of the species’ range on the Boro-Horo Mountain Ridge in the basins of the Nilki & Tshashi rivers. The known distribution of the species is shown in Fig. 22 .

Bionomics. The species generally inhabits meadow biotopes in the forest and low-alpine zones within the range of elevations between 1790–3400 m a.s.l. Most of specimens were collected from under stones.
